FDA Issues Warning Letters to Dietary Supplement Companies

On October 13, the US FDA announced the issuance of warning letters to five dietary supplement companies whose product labeling declares cesium chloride as an ingredient.  FDA considers these products to be adulterated, because they are labeled as containing a new dietary ingredient, cesium chloride, and the companies have not yet satisfied the conditions required to lawfully market a dietary supplement containing a new dietary ingredient.  Cesium chloride is sometimes promoted as an alternative treatment for cancer.  However, no cesium chloride containing products have been approved by FDA to make this claim.  Furthermore, cesium chloride has not been previously present in the US food supply in a non-chemically altered form.
